whichlatter View E, is the escutcheonplate on which a latch key lock K, of the Yale or equivalent typeis mounted, the spindle end thereof extendin throu h the base plate 6, of the casing box B, and into a slot is, in -the hub of the key thrust arm-lo, the

end of which projects into the notch a,

' formed in the upper portion of the primary segmental rocker A, as will be seen by reference more particularly to Figs. 30 and 31.

'lhesaid segmental rocker A, is-pivotally supported on the base plate 2),0f the casing box B, by means of a hollow boss 6, and retainin'g screw'b (see 'Figs'. "28 and 29) and is formed with rack teeth a, which engage with corresponding rack teeth 0, on the op posed edge ofthe lower or secondary seginental rocker C, which is likewise pivotally supported on the base plate b, in this'case on a hollow stud 6 (see Figs-28 and 29) through which the-handle spindle it, ex

' tends.

The upper primary segmental rocker A,

i is formed with a lateral arm a ,-which is a pivotally connected with alink (4 which 1n turn is'pi'votally connected with the lower extremity of the upper auxiliary brace 'bolt V,* which extends through the top flange of the casing box B, and to a guide cap cl,on-

the top of the door I), as shown in Fig. 1,

of the drawings, said guide cap cl, when the door is closed, being in alignment with the socket plate j, on the upper member of the door amb J, so that when the said auxiliary brace bolt V, is shot upward it.'wi ll engage with saidsocket plate'j, thereby reinforclng and securing the upper portion of the door against external pressure. i

In like manner the lower segmental rocker C, is formed'with a lateral armo", which is pivotally connected with a link 0 which in turn is pivotally connected with the upper extremity of the'lower' auxiliary bracebolt X, which extends through the lower side fiange'of' the casing box Band to a guide cap d, on the bottom of the door D, also as'shown in said Fig. 1, of thedrawings, said guide cape-d, when the door'is closed, being in alignment with the mortise plate and socket f, countersunkin the floor, so. that when the said auxiliary bracebolt 'X,

a is shot downward it willcngage with said mortise plate and socket f, thereby reinforcing and securing the lower portion of the door against external pressure.

' Thus th'e'two auxiliary bracebolts V, and X, are adapted to positively secure the door D, in closed and bolted position independent of although controlled by the otherbolt lock mechanism. In the "accompanying drawings these auxiliary brace bolts 'V, and

X, are shown as positioned and operating vertically, although they may be otherwise positioned and operated with substantially like results in adapting them to special rekey lock plate M, a suflicientdistance away from the base plate o, to afford accommodation for the key-aeliuited shift arm 70, the hub flanges of which are jou-rnalled respectively in a bearing hole 6*, formed for the purpose in the base plate Z), and in the bearng holem, in sai'dkey lock plate M,'as-

will be understood by reference more-part1cularly to F 1g.'28, of the drawings, which also shows the spindle tongue of the latch lock'K, protruding into the slot is, of said key-actuated shift arinla. Thus in Fig. 30, I

said key-actuated shift arm 70 is shown as inengagement with the notch a, of the pri-.

mary segmental rocker A, and as having rocked it into position'shown in Fig. 3, of the drawings, whereas Fig. 81, shows said primary segmental rocker A-,',as rocked into position shown in Fig. l, thereof.

Fulcrumed on and betweenthe said fixed lock plate Land the cover plate'B', of the box casing B, is thehand shift lever S, the shaft 8, of which is in axial alignment with thekey lock spindle terminal 70, and the hub of the key-actuated shift arm 70, the inner end of the rock shaft 8, Onwhich said hand shift" lever S, is rigidly mounted being journalled' in the aforesaid bearing hole/m, in the key lock plate M, andithe outer end of'said-rock shaft .9, being journalled in the bearing hole 6 formed for the purpose in the cover plate B,as clearly 4 shown inFig. 28, of the drawings, the protuberantouter end of said rock shaft .9, having rigidly attached thereto the finger switch. 3, by means of which said shafts,

and its'switch lever S, may berockedalternately in opposite directions to shift the spring pawl P, from one-mortise notch m, in the'key lock plate M, to the other mortise notch m therein and vice versa,said' spring pawl P, being connected with the handshift lever S, bymeans of a coupling pin 22, on the pawl P, which pin 10, protrudes into the longitudinal slots, formed for the purpose in the shift'lever S, as willbe-understood by reference more particularly to Figs. 3, 4L, 5 and 20,0f the drawings; if

The spring pawl P, is slidably mounted upon the face of the segmental rocker A, its shank 79, resting between fixed guide shoulders a a on the upper portion of. said primary segmental "rocker A, and its-stem rod- 39 engaging with anfeye lug a, on the lower portion of said primary segmental rocker A, adjacent to the gear teeth a, thereon, and a coiled spring 19 being interposed on said stem rod 10 between the eye lug a, and the shank p, of the pawl P, said spring tending constantly to maintain engagement of the nose'of said pawl with the key lock plate M. V

The spring pawl P, is formed, below the coupling pin 10, with a bearing shoulder 12*, for contactual engagement with the end of the hand shift lever S, when the latter is moved in either direction to shift the pawl P, and the primary segmental rocker A, on which it is mounted, said hand shift lever S, being of sufficient length to depress in' transit the pawl P, against the resistance of the spring 30 so that the nose of the pawl is released from the mortise notches m, m in the key lock plate M, to admit of the shifting of said primary rocker A, from one position to the other.

A lateral extension 19 of the spring pawl P, has rigidly secured to it apush rod or member 79, the upper end of which, when the parts of the locking mechanism are in the relative positions shown in Fig. 4, of

the drawings with the jamb mortise bolt I,

and auxiliary brace bolts E, Gr, shot, is in operative alignment with the ush button w, of an automatic alarm bell or equivalent sounding device, that indicated in the drawings being of a well known commercial spring motor type, and being fixedly mounted on an extension 5*, of the base plate I), of the casing B, as will be understood by reference more. particularly to Figs. '28 and 29, of the drawings. Hence, under these conditions, any attempt to force back either of the aforesaid bolts, will result in sulficient movement and pressure exerted upon and through the medium ofthe meshed segmental rockers A, C, to actuate said alarm device W, and thus frustrate surreptitious entrance.

The jamb mortise bolt I, is connected with the lower extension 0 of the secondary segmental rocker C, by means of a stud '5,

protruding into an elongatejslot 0*, in said extension 0 as indicated by dotted lines in Figs. 3 and 4, and in sectional elevation in Fig. 28, of the drawings.

L, is the spring snap latch formed with the usual bevelled outer end Z, and held normally thrust outward by means of'the leaf spring n, the lower end of which bears against the transverse shoulder Z, formed vfor the purpose on-the forward portion of said latch L,Y behind the snap bevel Z, the

rear portion of said latch Z, being formed with the longitudinal slot Z which straddles the axial sleeve a, integral with the duplex cam R, the arms of which engage contactually with the transverse abutment Z on the inner extremity of said spring snap latch L, as shown more particularly in latch L, against the resistance of its spring n, the upper portion of which latter is held fixedly upon the base plate 6, by binding contact with, and between the stud b and one ofthe bosses 6 on said base plate 6.

What I claim as my invention and de sire to secure by Letters Patent, is

In locking mechanism of the character designated, the combination of a cylinder look, a primary segmental rocker actuated thereby, a secondary segmental rocker con trolled and actuated by saidprimary segmental rocker, a amb mortise bolt connected with and controlled by said secondary segmental rocker, an auxiliary brace bolt connect-ed with and controlled by said primary segmental rocker, a brace bolt connected with and controlled by said'secondary segmental rocker, and an alarm 'soundingdevice operatable by a push member mounted on said primary segmental rocker, substantially in the manner and for the purpose set forth.
